Detailed Description
The technical solution of the present invention will be more clearly and completely explained by the description of the preferred embodiments of the present invention with reference to the accompanying drawings.
As shown in fig. 1, the robot anti-collision buffer assembly according to the preferred embodiment of the present invention includes a guardrail plate 1 and a plurality of buffer members 2, wherein one end of each buffer member 2 is connected to the guardrail plate 1, and the other end of each buffer member 2 is connected to a robot, and the robot is impacted on the guardrail plate 1 by force and buffered by the buffer members 2.
The buffer 2 comprises a shaft sleeve 3 and a connecting rod 4, wherein a sliding plate 5, a sliding ring 6, two small springs 7 with different elastic coefficients and a large spring 8 are arranged inside the shaft sleeve 3.
Connecting rod 4 and slide 5 fixed connection, connecting rod 4 is connected on guardrail board 1. The sliding plate 5 can slide along the axis of the shaft sleeve 3, a first sliding chute 9 for the sliding plate 5 to slide is arranged in the shaft sleeve 3, one end of the small spring 7 is in contact with the sliding plate 5, the guardrail plate 1 is impacted, and the sliding plate 5 presses the small spring 7 immediately. The sliding ring 6 is also arranged inside the shaft sleeve 3, the sliding ring 6 can also slide along the axis of the shaft sleeve 3, a second sliding groove 10 for the sliding ring 6 to slide is arranged inside the shaft sleeve 3, and the length of the first sliding groove 9 is longer than that of the second sliding groove 10. The sliding sleeve can be contacted with the sliding ring 6 only after sliding a certain distance along the shaft sleeve 3. One end of the large spring 8 is in contact with the slip ring 6, and the movement of the slip ring 6 compresses the large spring 8.
